background

• After updating cocos2dx from v3 to v4, there was a bug that the screen was not drawn properly when the screen orientation of the device was changed
  • As I posted in the forum, I solved the problem by regenerating the CCEAGLView, but there was a problem with the drawing, so I had to do a root solution

Cause of the problem

It turns out that the cause of the problem is that the layer of CCEAGLView is CAMetalLayer, and CAMetalLayer.drawableSize is not updated when CCEAGLView.layoutSubView is used.

Revision details

Fixed to resize CAMetalLayer on CCEAGLView layoutSubviews.

How to change the size? From portrait to landscape?

How to change the size? From portrait to landscape?

@minggo The size of the layer changes when the screen is rotated, assuming that the application has been implemented to support portrait and landscape. Specifically, we call the setFrameSize and setDesignResolutionSize api of GLView to change the size when the screen is rotated.

Got it, thanks.
